WATERi-*CLOSET FLUSH-ING APPARATUS.

SPECIFICATION forming part of Letters Patent No.A728,47O, dated May 19, 1903.

l Application filed January 9, 1903. Serial No. 138,442. (No inodel.)

To @ZZ whom, t may concern:

Be it known that I, AUGUSTIN KULHNEK, a subject of the Emperor of Austria-Hungary, residing at Prague VII-830, Kingdom of Bohemia, Austria-Hungary, have invented certain new and useful Improvements in Water- Closet Flushing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the iiguresof reference marked thereon; which form a part of this specifica.- tion.

The object of this invention is toprovide a iiushing device for water-closets of simple, strong, and durable construction, reliable in operation, and adapted to save water.

The invention consists in the improved flushing device, in combination with the wellknown siphon and swimmer arrangements, substantially as will be hereinafter more fully described and at the end embodied kin the clauses of the claim.

Referring to the` accompanying drawings, in which like numbers of, reference indicate corresponding parts in each of the several views, Figure l is avertical section of the flushing device in a front view. Fig. 2 is an axial vertical sectionv of the same object in 'a side view. Fig. 3 is a sketch of the same object, on a smaller scale, as mounted in the siphon orilushing-pipe,showing the usual siphon-tank 1 onthe top.

The usual siphon 2 inside the tank lA is connected with the flushing-pipe 3, in which is interpolated the flushing device. This consists of a chamber or receptacle 4:, the rear side of which forms a bearing for the horizontal shaft 5, while in the front a second bearing is provided in support 18. The -front of chamber or receptacle 4 is closed by an appropriate covering. Upon the shaft 5 is fulcrumed eccentrically theY bucket 6, havin-g its center of gravity on one side of the axis 5, while on the opposite side a secondary bucket 7 is fastened onto the bucket 6. The smaller or secondary bucket 7 is calculated s o as to equalize and counteract the weight of the chief bucket 6 if both are filled with water;

side.

but the secondary bucket 7 is provided on its against the corresponding side of the tooth Y l0, which keeps it in its position as long as the tooth l0 is not withdrawn. Tooth 10 can swing, but only in one direction, around a pin ll, which is parallel to the axis 5. Referring to Fig. l, it can pivot from left to right, but

not from right to left. The perpendicular piece 12, in which the tooth is pvoted, can turn on a pin 13, which also is horizontal, but perpendicular to pin 11. Piece 13 can be turned out of its normal position by means of a push-buttonY 14 or the like device from out- This pulls tooth 10 aside, so that butt 9is free to proceed on its way if the overweight of the' filled bucket 6 turns it. It is evident that in this case the bucket turns around andempties its contents into the flushing-pipe 3. The downturning bucket 6 abuts below into the iiXed piece l5, limiting its throw, and turns back again,`being free from its overweighing-water. A counterweight 16 is fastened to it on the side which is opposite to the fulcrum of 6 for the purpose of assuring its return into the neutral position, in which, if filled with water, it is held fast by the said tooth 10, which yields in one direction, allowing the butt 9 to catch it, but does not let it free in the opposite direction, exceptif it is pushed aside by pushing the button 14, as before said. In the meantime the water iiushing from the bucket 6 down to the flushing-pipe 3 forms a sucking-piston in the latter and sucks water from the tank l through its siphon 2, which continues, therefore, to iiush down as long as the provision of water in the said tank allows and as long as no air comes into the siphon. This flush of water falls over the division-wall 17 and fills both the chief bucket 6 and the secondary bucket 7.

The buckets 6 and 7 cannot be emptied as long as this flush lasts, and this cannot cease as long as the inlet of the siphon 2 is dipped in Water. The level of the water in the tank 1 sinks speedily, and as soon as the inlet of the siphon is uncovered the flush ceases completely and tank 1 begins to till itself anew, which takes place in the known way. The water from the secondary bucket 7 Hows 0E through the small opening 8 in its bottom. Up to this moment no`pushing of the button 14 could have produced a new ilushing,.be cause as long as the secondary bucket 7 is filled with water no overweight takes place on the opposite side. It would have been, therefore, of no effect if some person would try to produce liushes repeatedly by pushing the button 14, as one would be obliged to hold this button down the whole time till after the completed flush all the water from the secondary bucket 7 would tlow out through the small opening 8 in its bottom. The natural consequence is a great saving of water, because its flushing will surely not be unnecessarily repeated, nor can it be made to last practically longer than the time for which it has been calculated.

One needs, therefore, only to push the button 14 in after each use of the water-closet and then let it spring back again. Then the flush takes place instantly and regularly. Should for any reason the action ofthe device cease, a single filling of the tank 1 and of the bucket 6 with water would suffice to make it play again. rllie bucket will right itself almost instantaneously after dumping or before the water from above enters the chamber 4; but it' the Water is liowing through the chamber'it is deflected by the wall 17, so that the tendency is to right the bucket.

Should in any case a continuous Iiushing be desirable, then the swimmer in the tank 1 can be held up or one would in any other known way have to provide for continuous supply of water.

It will be understood that tank 1 or any other device for providing the water as required for the flushing can be placed anywhere, either in the same locality with the water-closet or outside the same.

Itis obvious that various alterations can be made Without changing the scope of my invention. Therefore I do not intend to limit myself to the precise construction shown and described; but

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a iiushing device, of a flushing-pipe, a chamber in said pipe, a tilting bucket pivoted in said chamber, an auxiliaryreceptacle on oneside ofsaid bucket, a drain for said receptacle, a counterweight adapted to return said tilting bucket to normal position, a stop on said bucket to hold it in upright position, a pivoted catch for said stop, and means for throwing said catch out of engagement.

2. In a flushing device for water-closets and the like, the combination of a vertical flushpipe, a chamber in said pipe, a tilting bucket pivoted in said chamber, adapted to turn in discharging toward one side of the chamber, an auxiliary bucket secured to said bucket on the side opposite to its discharge side, and adapted to hold sufficient water to balance said tilting bucket when both are iilled, a minute discharge for said auxiliary bucket, a counterweight adapted to return the bucket to normal position, a stop on said bucket, a pivoted catch for said stop, a plunger operated by a push-button for disengaging said catch and stop, and a deflecting-wall in said chamber beneath the inlet-orifice adapted to deiiect the water toward the side of the chamber opposite to that toward which the bucket tips.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUSTIN KULHNEK.
